Default Re: Manifold vacuum at idle... vs without...interesting observations

Kilo,
This happens all the time.........had '51 Merc in the shop with lag complaints,
timing was on the money mark wise, reset the dwell, changed the accel pump all for
nothing. I bumped the timing up a bit, took the Merc out it was better ,4th trip out it was real happy....same thing ,the pointer and mark were way off, but the Merc ran like it should....I remarked the pulley.
